  • the assignment information for a codeword is signaled independently of the other codeword's assignment information, then the signaling requirements are substantially increased. For example, if the transport block size (TBS) for each codeword is indicated by six bits in an assignment, then the dual codeword operation requires twelve bits for TBS signaling.

  • These assignment parameter fields 210 , 220 and 230 included in the downlink assignment message 200 are signaled from the Node-B 110 to the WTRU 120 via a physical downlink control channel (PDCCH).

  • the assignment message 200 may also be applicable for transmission via an uplink channel.
  • overhead is reduced for signaling the modulation and the number of codewords in a downlink signaling assignment.
  • a plurality of bits (such as three bits), are used to jointly indicate the number of codewords (i.e., streams) used in the downlink communication of E-UTRA and the modulation type used for those one or two codewords.
  • FIG. 3 shows a downlink signaling procedure 300 according to the first embodiment.
  • the Node-B 110 determines the modulation scheme to use (step 310 ).
  • the Node-B 110 determines the number of bits for the TBS.
  • the Node-B 110 determines which HARQ process is to be used.
  • FIG. 3 shows three separate decisions or determinations, 310 , 320 , 330 in a specific order, those of skill in the art would understand that this is for ease of explanation. One decision, or multiple decisions in a different order, may be made.
  • the Node-B 110 signals the modulation types, the TBSs and the HARQ process ID parameters via a downlink channel, (such as the PDCCH), to the WTRU 120 .
  • the WTRU 120 uses the parameters received from the Node-B 110 in detecting and decoding received downlink data.
  • the codeword modulation signaling described in this embodiment is summarized in Table 1.
  • the number of bits used for the TBS and the HARQ process IDs may also be reduced as discussed in the second and third embodiments, respectively.
  • FIGS. 4A-4C illustrate a second embodiment, whereby overhead is reduced for signaling the TBS when dual codewords are used.
  • the TBS of the primary codeword 410 is indicated using six bits, and a lesser number of bits (five, in this example) are used to indicate the TBS of the secondary codeword 420 .
  • a lesser number of bits for the TBS of the secondary codeword may be made possible, for example, by reducing the resolution of the TBS for the secondary codeword 420 .
  • the same primary codeword 410 is used, and a secondary codeword 430 having three bits is used to indicate the difference between the TBS of the primary codeword 410 and the secondary codeword 430 .
  • the difference between the TBS of the primary codeword 410 and the TBS of the second codeword 430 i.e., three bits is signaled, instead of only signaling the TBS of the second codeword.
  • the same primary codeword 410 is used, and a secondary codeword 440 having four bits is used to indicate the difference between the TBS of the primary codeword 410 and the secondary codeword 440 .
  • each single codeword uses N HARQ processes, that results in an overhead of ⁇ log 2 N ⁇ bits. Dual codeword operation therefore uses 2N HARQ processes.
  • the number of codewords may be indicated by other signaling such as for the MCS, TBS, precoder information, and the like.
  • a first alternative implements a fixed division of the HARQ processes that are used for the primary and the secondary codewords.
  • the primary codeword may use only HARQ processes 1 , 2 , . . . , N
  • the secondary codeword may use only HARQ processes N+1, N+2, . . . , 2N.
  • the signaling overhead is 2 ⁇ log 2 N ⁇ bits.
  • non-equal numbers of HARQ processes may be assigned to each codeword.
  • a second alternative for reducing downlink signaling overhead for HARQ process IDs allows limited pairs of HARQ processes ( ⁇ 1 a, 1 b ⁇ , ⁇ 2 a, 2 b ⁇ , . . . , ⁇ Na, Nb ⁇ ) for a primary and secondary codeword pair.
  • any single HARQ process i.e., 1 a, 2 b, etc.
  • the signaling overhead is ⁇ log 2 N ⁇ +1 bits determined by the single codeword case.
  • the signaling overhead in the second alternative is dominated by the single codeword case.
  • the dual codeword uses less signaling overhead.
  • the amount of signaling is greatly reduced. If the number of codewords is two, then extra pairs in addition to the pairs of the HARQ processes used in the second method are added for the dual codeword to increase flexibility in usage of the HARQ processes. Extra pairs allow the transmission of misaligned HARQ processes on the two codewords.
  • This third alternative, shown in Table 3 has the same overhead as the second alternative, but has less restraint in usage of the HARQ processes.
  • An evolved Node-B may realign the HARQ process IDs of the two codewords whenever the misalignment between HARQ process IDs of the two codewords is larger than a predetermined threshold. Therefore, the impact of the HARQ process ID signaling described above has the least limitation and impact on usage of the HARQ processes.
